METHOD OF COOLING COI LS OF GAS-CONDENSERJS.

SPECIFICATION forming part of Letters Patent No. 313,0k7, dated March 3, 1885.

App'ication filed S ptember 29, 1884. (No model.)

To (LZZ whom it may concern:

Beit known that I, VIc'roR H. BECKER, residing at Memphis, in the county of Shelby and State of Tennessee, and a citizen of the United States, have invented a new and useful Improvement in the Method of Cooling Coils of GasCondensers, of which the following is a full description, reference being had to the accompanying drawings.

It is common to condense ammoniagas by passing it through coils located in a tank, through which tank water flows to cool the coils. I have discovered that the water which is in immediate contact with the coils has a tendency to remain in contact therewith, and does not, even after it becomes warnnpass off freely.

The object of my invention is to overcome this difficulty, which I accomplish by introducing air into the tank near the bottom, which in its passage through the water agitates the same, and, coming in contact therewith and \viththe coils, takes up and carries oh the heat.

In the accompanying drawings I have illustrated a mechanism which maybe used for the purpose specified, in which drawings Figure l is a plan; Fig. 2, an elevation.

In the drawings, A represents a tank,'in which are located a number of coils, B, one end of each coil being connected with ahead er, 0, and the other end with a header, D.

a is a pipe through which gas is conveyed to the header 0, and b a pipe from which the condensation is carried away from the header I). i.

E is a pipe through which water is supplied to the tank, the water passing into the header 0 and out therefrom through openings e.

f is an overflow-pipe.

Thus far the parts described may be constructed in the ordinary manner.

F is an air-pipe communicating with th 5 header G, located, as shown, in the tank.

with the header G and the other end being preferably closed. One of the pipes 9 passes underneath each of the coils B, and each pipe 9 is provided with a number of holes, h.

In use air is to be forced by any suitable means through the pipe F into the header G, from which it will pass into the pipes g, and from them into the tank through the holes h. This air, so forced into the tank through the pipes y, will pass up rapidly through the water and about the coils, agitating the water and taking up the heat therein and carrying it away, the air escaping from the upper sur face of the water in the tank, which is open at the top. Air might be forced into the tank in other ways. For example, an air-tube might be provided, communicating with the suctiontube from the pump which supplies water to the tank, and then air would be pumped into the tank with the water, in which case it would be advisable to provide the header 0 with a series of tubes passing under the several coils B, each tube being provided with perforations, through which the water and air could pass into the tank. If this plan shouldbe adopted, the air-tube F, header G,and tube 9 need not be used.

Theleading object ofthis invention is to condense ammonia-gas in connection wit-h icemaking machinery. Gas is pumped into the coils under pressure. By introducing air into the water which surrounds the coils a less quantity of water will be required, and the gas will also be liquefied under less pressure.

\Vhat I-claini as new, and desire to secure by Letters Patent, is-

As an improvement in cooling the coils or )i es of a 'ascondenser the )rocess which a 7 l described.
